Relationships between pulmonary dead-space fraction (VD/VT) and the microcirculatory blood flow at baseline and 24 h after. a Scatter plot depicting the correlation between pulmonary dead-space fraction (VD/VT) and the proportion of small vessels perfused at baseline. b Scatter plot depicting the correlation between pulmonary dead-space fraction (VD/VT) and the proportion of small vessels perfused 24 h after. c Scatter plot depicting the correlation between pulmonary dead-space fraction (VD/VT) and MFI at baseline. d Scatter plot depicting the correlation between pulmonary dead-space fraction (VD/VT) and MFI 24 h after. PPV: percentage of small vessels perfused; VD/VT: pulmonary dead-space fraction; HI: heterogeneity index of microcirculatory blood flow; MFI: microcirculatory blood flow index
